LG Display says FLiPP process could improve OLED output and cut costs
LG Display says it has developed a new way to pattern OLED screens called FLiPP.
The process is designed to work without the fine metal masks used in conventional OLED manufacturing.
Instead, it deposits OLED material across a glass sheet and uses a protective layer and ultraviolet light to remove material where it is not needed.
LG says this can increase the share of a screen that emits light by 55% compared with the mask-based method.
It says the process could also make screens brighter, extend their life or reduce power use, and improve how many panels can be made from a sheet of glass.
The company says it can use existing production facilities, avoiding some of the cost of building a new line.
LG plans to start with panels for tablets and laptops, then consider wearable devices and TVs.
LG Display said its FLiPP OLED patterning process could improve production efficiency and reduce costs.
The company said the process avoids fine metal masks by depositing organic light-emitting material across a substrate and removing unwanted areas with ultraviolet light.
LG Display said the process can raise the pixel aperture ratio by 55% compared with the existing fine metal mask method.
For 23.5-inch panels made at an eighth-generation facility, the company estimated FLiPP could achieve at least 93% material-use efficiency, versus about 75% with the half-cut fine metal mask method.
LG Display plans to begin applying the process to IT panels, including tablets and laptops, and later expand it to wearables and TVs.
- Who
- LG Display.
- What
- The company said its FLiPP OLED patterning process could improve performance and production efficiency while reducing costs.
- When
- LG Display presented the process at an online seminar on October 8, 2026.
- Where
- Online. The company is based in South Korea.
- Why
- LG Display said FLiPP can avoid fine metal masks, use existing production infrastructure and make better use of glass substrates.
This story does not have two clearly opposing sides.
FLiPP started from removing the technological limits that had blocked the possibilities of OLED.
Unlike the 8.6-generation process, which requires the mother glass to be cut in half, FLiPP uses the glass as it is without cutting it, so more panels can be produced from one sheet of glass, improving material-use efficiency.
LG Display held an online FLiPP technology seminar.
Yonhap and Chosun Ilbo published reports on LG Display’s FLiPP process.
LG Display said it plans to apply FLiPP to IT panels first, then expand it to wearables and TVs.
- Aperture ratio
- 55% higher than with the existing fine metal mask method, according to LG Display
- Brightness
- Could be increased by 1.6 times, according to LG Display
- Lifespan
- Could be increased by 2.4 times, according to LG Display
- Power consumption
- Could be reduced by 13%, according to LG Display
- 23.5-inch panels
- Estimated material-use efficiency of at least 93% with FLiPP, compared with about 75% with the half-cut fine metal mask method
- Application plans
- IT panels first, followed by wearables and TVs
